IMPROVEMENT lN BED-SPRINGS.

The Schedule :aimed to in these Letters Patent and making part of thelame.

To all whom it may concern Be it known that I, DELOS V. GRANDALL, 0i'the city of Chicago, in the county of Cook and State of Illinois, haveinvented certain new and useful Improve'- lnents in Bed-Springs; and Ido hereby declare the following to be a full, clear, and exactdescription ofthe same,rei'e1ence being had to the accompanying drawingforming part of this specification, in Which- Figure l is a top planView of my improved bedspring, and

i Figure 2 is a side elevation ofthe plate for securing the spring to aslnt or rail.

Similar' letters ot' reference in the drawing indicate correspondingparts.

My invention has for its object to improve the means for attachinghelical springs to bed-slats, rails, &c., -for which Letters Patent ot'the United States were granted to me April 3, 1866, numbered 53,579. Insaid patent the lower portion ot' the helical coil is received inaholein the slat and secured in place by a plug.

As this construction is lsomewhat objectionable,A

from the fact that the slats are weakened by cutting the holes, Ipropose to leave the slats uncut and to secure the bottom ofthe springsto the slats by means of'. screws or rivets passing through a metalplate attached to said spring.

In the accompanying drawing- A is the coiled spring, to the apex ofwhich is firmly secured the metal plate B, as shown, with the ends Gbent over two opposite sides of the spring.

rlDhe spring is secured to the Slat E by means of one or more screws orrivets, D, passed through the plate into the slat, as fully shown in thedrawing.

Having thus described my invention,

What I claim as new therein, and desirel to secure by Letters Patent, is

Goiled bed-springs, secured to slats or rails by means of the metalplate B and one or more screws or rivets, substantially as described,for the purpose 'lhe above speciiicatiou of my invention signed by methis 19th day of September, 1870.

DELOS Y. GRANDALL.
